Subcutaneous Emphysema following Emergent Surgical Conventional Tracheostomy.

In maxillofacial surgery, tracheostomy is indicated in congenital, inflammatory, oncologic, or traumatic respiratory obstruction. In traumatic cases, however, it is sometimes hard to implement. We describe subcutaneous emphysema following emergent surgical conventional tracheostomy performed after stab injury to the floor of the mouth.

The treatment of large sialoliths by sialendoscopic combined approach.

Purpose: To investigate the advantages, disadvantages, and complications of the combined surgical technique for removing large sialoliths from the salivary glands.

Materials And Methods: This retrospective study analyzed 37 patients with obstructive sialadenitis caused by sialolithiasis who could not undergo surgery using a purely sialendoscopic technique because of the stone size or because of a tight distal stricture obstructing the passage of stone removal by an endoscope.

Results: Six patients had parotid gland obstruction, and the other 31 patients had submandibular gland obstruction.

The use of sialendoscopy for the treatment of multiple salivary gland stones.

Objective: The purpose of this study is to document our experience with sialendoscopy for the treatment of multiple calculi of the salivary ducts, as well as to discuss the technique and indications for the procedure.

Patients And Methods: In this retrospective non-interventional study, 530 consecutive cases of sialolithiasis were investigated, and the cases with multiple calculi were selected for further analysis. These selected cases were analyzed from clinical and surgical aspects.

Chronic obstructive parotitis due to strictures of Stenson's duct--our treatment experience with sialoendoscopy.

Purpose: The present retrospective analysis was performed to assess the effectiveness of sialoendoscopic treatment of chronic obstructive parotitis.

Materials And Methods: The study group included 87 parotid glands with stricture as the only cause of gland obstruction. After sialographic and sialoendoscopic evaluation, sialoendoscopic 4-step surgical treatments were performed.

The clinical significance of sinus membrane perforation during augmentation of the maxillary sinus.

Purpose: Augmentation of the maxillary sinus floor is a well-documented technique and is generally accepted as a pure implantology procedure to facilitate placement of dental implants in the posterior atrophic maxilla. The objective of this report was to evaluate the significance of the sinus membrane perforations on the incidence, complications, and success rate of this procedure.

Patients And Methods: Patients who received sinus floor augmentation and simultaneous placement of dental implant were included in this study.

Synovial chondromatosis of the temporomandibular joint: report and analysis of eleven cases.

Purpose: Synovial chondromatosis (SC) is a benign monoarticular condition that is uncommon in the temporomandibular joint (TMJ). The purpose of this article is to present 11 additional cases of SC of the TMJ and discuss newer modes of imaging, diagnostic approaches, treatment options, and follow-up data.

Methods: Medical records of 11 patients with SC treated within our department from 1991 to the present were reviewed.

The use of free fibular flap for functional mandibular reconstruction.

Purpose: The purpose of this investigation is to document our experience using the free vascularized fibular flap for comprehensive reconstruction of discontinuity defects in the mandible, after combined resections of malignant and aggressive odontogenic tumors, with special emphasis on functional aspect of the reconstruction process.

Materials And Methods: The study group consisted of consecutive patients treated for reconstruction of discontinuity defects of the mandible, using the fibular vascularized free flap, between 1997-2002. All procedures were performed in the same hospital and by the same surgical team.

Comparing the effects of V-Y advancement versus simple closure on upper lip aesthetics after Le Fort I advancement.

Purpose: The aim of this study was to compare upper lip movement and its dimensional changes after maxillary advancement via Le Fort I osteotomy, using V-Y advancement versus simple continuous closure. The study investigates dimensional changes in the superior and inferior portions of the upper lip, as well as changes in lip length, resulting from the procedure.

Patients And Methods: The study group consisted of 35 patients who had undergone 1-piece Le Fort I osteotomy for maxillary advancement of 3 to 6 mm with less than 3 mm of vertical changes.

Dental implants in patients with type 2 diabetes mellitus: a clinical study.

Purpose: Systemic factors, such as diabetes mellitus, can influence the success rate of dental implants. The authors describe their experience using the MIS implant system (Medical Implant System, Shlomi, Israel) for retention of overdentures in patients with type 2 diabetes mellitus and provide data regarding the level of satisfaction of the patients, the improvement of function, mucosal and periimplant health, and bone level around implants in this group.

Methods: The study group consisted of 41 patients with type 2 diabetes mellitus who received 141 implants for retention of overdentures.

Periodontal changes in liver cirrhosis and post-transplantation patients. II: radiographic findings:

Background: Liver disease and transplantation affect bone turnover. The role of cylosporin A (CsA) in aggravating bone loss is controversial. The aim of the present study was to examine the effect of liver cirrhosis, transplantation, and immunosuppressive therapy with either CsA or tacrolimus on alveolar bone height.

Factors influencing oral colonization in premature infants.

Background: Factors influencing the oral flora of premature infants have not been adequately investigated.

Objective: To investigate the effects of gestational age and of anti-bacterial therapy on the oral flora of premature infants.

Methods: Oral cultures were obtained at age 1 day and age 10 days from 65 premature infants, divided into three groups: a) 24 neonates of 30-34 weeks gestation who did not receive ABT, b) 23 neonates of 30-34 weeks gestation who received ABT, and c) 18 neonates < 30 weeks gestation who received ABT.
